About
Ji Yeong Lee is a robotics researcher whose work focuses on motion planning and autonomous navigation for robots operating in complex three-dimensional environments. Her most notable contribution is the development of the rod hierarchical generalized Voronoi graph (rod-HGVG), introduced in her 2005 paper "Sensor-based Planning for a Rod-shaped Robot in Three Dimensions: Piecewise Retracts of R³ × S²." This work presents an innovative roadmap framework for rod-shaped robots navigating unknown three-dimensional workspaces, addressing the particularly challenging configuration space diffeomorphic to R³ × S², which encodes both position and orientation. By constructing piecewise retracts, Lee provided a principled method for path planning without requiring prior knowledge of the environment, a significant advance for sensor-based robotics. The paper has accumulated 10 citations, reflecting its specialized but meaningful contribution to the geometric and topological foundations of robot motion planning. Lee's research sits at the intersection of computational geometry, topology, and autonomous systems, offering theoretical tools that underpin practical navigation solutions for non-trivial robot morphologies in real-world settings.
